Explanation:

Question 1

To determine the correct answer for "A renewable resource is one that", we analyze each option:

• Option A: Renewable resources can be depleted if overused, so "never runs out" is incorrect.
• Option B: By definition, a renewable resource is one that can be replaced naturally (e.g., solar, wind, water are replenished naturally). This matches the definition.
• Option C: Renewable resources are natural (e.g., sunlight, wind), not man - made, so this is incorrect.
• Option D: The cost of a resource is not related to its renewability, so this is incorrect.

To find the non - renewable resource, we know:

• Option A: Wind is a renewable resource as it is constantly replenished by natural processes.
• Option B: Solar energy is renewable as the sun's energy is continuously available.
• Option C: Coal is a fossil fuel formed over millions of years. Once used, it cannot be replaced in a human - time scale, so it is non - renewable.
• Option D: Water is a renewable resource as it is part of the water cycle and is replenished.

To define "Conservation", we analyze the options:

• Option A: Using resources quickly is the opposite of conservation, which is about sustainable use.
• Option B: Conservation means protecting resources wisely to ensure their availability for future generations. This is in line with the concept of resource conservation.
• Option C: Avoiding all resource use is not practical and not what conservation is about (we need to use resources for survival and development, but wisely).
• Option D: Conservation is about protecting existing resources, not creating new ones.

Answer:

B. Can be replaced naturally
